According to this page: https://formlabs.zendesk.com/entries/24114696-How-to-Glue-Parts-and-Repair-Small-Holes
…it’s suggested that a laser pointer can be used to cure resin used to repair a part. I found a couple of laser pointers meeting the specs listed and I was wondering if the color mattered (e.g., green or violet)? And if so, which is recommended for this purpose.
Thanks in advance for your answer.

405nm is violet. Also sometimes referred to as a blu-ray laser (it’s the wavelength in blu-ray players/burners.)
Hi Jonathon,
Thanks for responding. What was confusing me is that a search on Google shows 405nm lasers coming in a variety of colors and not just violet.
That said, this issue had been clarified for me in this thread: https://support.formlabs.com/entries/23694611-Resin-Laser-Pointer-Awesome-Glue-
Lots of other good part repairing info there too. (I see you’ve posted there, so this tip is mainly for other users who stumble on this thread.)

I’ve been using UV LED flashlight, I’ve found it hardens the resin within seconds and can do a much larger area
(also possibly safer).
